CGW 42544 5" X 7/8" Type 27 60-Grit XL Z3 Zirconia Flap Disc

CGW 42544 is a 5-inch diameter, 60-grit Type 27 zirconia flap disc designed for aggressive material removal on steel. The flap disc combines premium zirconia alumina grain with a poly/cotton backing, delivering durable stock removal while promoting a smoother finish through the backing’s flexibility. The zirconia concentration and abrasive blend are chosen to sustain cutting efficiency under heavy-duty use, and the included active grinding aid helps maintain cooler cutting action under light pressure, aiding workpiece control and extending disc life under demanding grinding conditions.

Engineered for high-performance stock removal, this flap disc is positioned for fast material removal in steel applications and is suitable for aggressive grind-and-sand tasks where both efficiency and controlled finish matter. The Type 27 profile provides a flatter grinding surface intended for use on angled contact with the workpiece, which helps achieve a more consistent finish across contoured or large flat areas. The combination of grain, backing, and construction is intended to balance aggressive cutting with a degree of surface quality suitable for subsequent finishing steps.

Compatibility and packaging details indicate a 5" disc with a 7/8" arbor/shank size and a maximum RPM rating of 12,200, making it suitable for compatible right-angle grinders. Each disc is packaged individually, with bulk boxes available for ordering convenience. When using this disc, follow standard safety practices for grinding: verify proper grinder RPM compatibility, secure the workpiece, and wear appropriate PPE. Regular inspection of the flap disc for wear and disc condition is recommended to ensure consistent performance and to determine when replacement is warranted.
